Merge pull request #2808 from rear/jsmeix-exclude-watchdog
|
|
|
2f081d |
|
|
|
2f081d |
Exclude dev/watchdog* from the ReaR recovery system:
|
|
|
2f081d |
In default.conf add dev/watchdog* to COPY_AS_IS_EXCLUDE
|
|
|
2f081d |
because watchdog functionality is not wanted in the recovery system
|
|
|
2f081d |
because we do not want any automated reboot functionality
|
|
|
2f081d |
while disaster recovery happens via "rear recover",
|
|
|
2f081d |
see https://github.com/rear/rear/pull/2808
|
|
|
2f081d |
Furthermore having a copy of dev/watchdog*
|
|
|
2f081d |
during "rear mkrescue" in ReaR's build area
|
|
|
2f081d |
may even trigger a system crash that is caused by a
|
|
|
2f081d |
buggy TrendMicro ds_am module touching dev/watchdog
|
|
|
2f081d |
in ReaR's build area (/var/tmp/rear.XXX/rootfs),
